Have you ever been asleep and wake up with no memory of sending a text message, shutting off an alarm, or had a conversation with someone and not rember it at all? Well you may be 1 of every 7 people thought to be suffering from "Sleep Drunkeness". According to researchers from Stanford University Sleep Drunkeness other wise know as confusional arousal is when a person wakes up and remains in a confused state for a certain period of time before either going back to sleep or fully waking up. According to the National Institutes of Health, this usually happens when someone is awakened during non-rapid eye movement (REM) sleep. Usually triggered by a forced awakening, like an alarm or phone call which causes them to be in a state of confusion for up to 15 minutes.
This typicaly happens to individuals whom are shift workers shuch as police officers, doctors, or others whom don't have a regular work schedule and need naps through out the days to compensate for sleep loss. One way researchers say to combat this "Sleep Drunkeness" is to allow 15 minutes after waking up to allow for your self to wake up fully before having to taskes requiring emense concentration just as driving a car.
